How to get the body response in a request

Question

I'm trying to make a webserver that will work like a proxy. My server make requests (POST, GET ...) for the client to an specific site, receive the response from this site and give it to the client. As i said, like a proxy. The problem is: in the response from google.com for example (or any other site) i can't read the body. The status code is 200 but when i tried to read the body content i receive weird things.

This is the part of my code that i make the request

request, err := http.NewRequest(method, url, nil)
for k, v := range m {
    request.Header.Set(k, v)
}
if err != nil {
    log.Fatalln(err.Error())
}

client := http.Client{}
resp, err := client.Do(request)

if err != nil {
    log.Fatalln(err.Error())
}else{

fmt.Println("=======================")
fmt.Println(resp)
fmt.Println("=======================")
fmt.Println(resp.Body)

And i receive this:

=======================

From the documentation at https://golang.org/pkg/net/http, to read the body of the response you can use io.ReadAll.

resp, err := http.Get("http://example.com/")
if err != nil {
        // handle error
}
defer resp.Body.Close()
body, err := io.ReadAll(resp.Body)

Side note: You can also use ioutil.ReadAll instead of io.ReadAll, but the ioutil documentation says:

As of Go 1.16, the same functionality is now provided by package io or package os, and those implementations should be preferred in new code.
